A few of my aquarium fish started to suffer from fin and tail rot. My traditional remedies were not curing their ailments. I bought this product, Kordon Methylene Blue, and performed a "bath" ( removing fish from aquarium and transferring them to a separate container for treatment ), and the fish are getting better ( one fish has totally healed ). Note that this product should not be added to the display aquarium due to staining of the tank seals and it being a detriment to beneficial bacteria. Highly recommended.

I have lost 4 tankfuls of fish. Once because of a horrible fungus on a plant. Once because of ich on a shipment of fish. Now I use this, in a separate tank for anything new I get. No more problems. The better fish sellers put a drop in the bag, so you know they are healthy. Watch out though. It turns your skin a lovely shade of blue. ;-)

I actually use this 'off label' to tint my white towels blue. It's not permanent dye but has nice color.

I'm sure it works I couldn't use it on my aquarium because I have a catfish so I had to use other remedies that are natural but I'm sure it will work on regular fish with scales
